I like to do all those things, but I really most enjoy building models of structures and buildings and I like the challenge of texturing, lighting and putting them in a realistic environment. I find that Carrara has the tools to allow me to do that. I'm learning to animate scenes as well. I do most of my modeling in Wings; force of habit, but I also have Hexagon and Carrara is no slouch. I've produced a few models on request for folks using mostly other apps.
